Why do my apps close down straight after opening them?

When I try to open certain apps such as Messenger, Facebook and Music, they switch to the loading screen before going straight back to the start screen. This has been happening for a few days now and I've already tried turning it off and on again (spoiler: it doesn't work). I've also tried to delete the apps but it won't allow me. Has anybody got an idea on how to fix it? :/
